Managed Identity names should meet naming requirements.


When naming Azure resources, resource names must meet service requirements. The requirements for Managed Identity names are:

  • Between 3 and 128 characters long.
  • Letters, numbers, underscores, and hyphens.
  • Start with letters and numbers.
  • Managed Identity names must be unique within a resource group.


Consider using names that meet Managed Identity naming requirements. Additionally consider naming resources with a standard naming convention.


This rule does not check if Managed Identity names are unique.
